Wireless Module Interface (WMI) Documentaion
This section describes the format and the usage model for WMI control and
data messages between the host and the AR6000-based targets. The header
file include/wmi.h contains all command and event manifest constants as
well as structure typedefs for each set of command and reply parameters.
Data Frames
The data payload transmitted and received by the target follows RFC-1042
encapsulation and thus starts with an 802.2-style LLC-SNAP header. The
WLAN module completes 802.11 encapsulation of the payload, including the
MAC header, FCS, and WLAN security related fields. At the interface to the
message transport (HTC), a data frame is encapsulated in a WMI message.
WMI Message Structure
The WMI protocol leverages an 802.3-style Ethernet header in communicating
the source and destination information between the host and the AR6000
modules using a 14-byte 802.3 header ahead of the 802.2-style payload. In
addition, the WMI protocol adds a header to all data messages:
{
INT8 rssi
The RSSI of the received packet and its units are shown in db above the
noise floor, and the noise floor is shown in dbm.
UINT8 info
Contains information on message type and user priority. Message type
differentiates between a data packet and a synchronization message.
} WMI_DATA_HDR
User priority contains the 802.1d user priority info from host to target. Host
software translates the host Ethernet format to 802.3 format prior to Tx and
802.3 format to host format in the Rx direction. The host does not transmit the
FCS that follows the data. MsgType differentiates between a regular data
packet (msgType=0) and a synchronization message (msgType=1).
Data Endpoints
The AR6000 chipset provides several data endpoints to support quality of
service (QoS) and maintains separate queues and separate DMA engines for
each data endpoint. A data endpoint can be bi-directional.
Best effort (BE) class traffic uses the default data endpoint (2). The host can
establish up to two additional data endpoints for other traffic classes. Once
such a data endpoint is established, it sends and receives corresponding QoS
traffic in a manner similar to the default data endpoint.
If QoS is desired over the interconnect, host software must classify each data
packet and place it on the appropriate data endpoint. The information
required to classify data is generally available in-band as an 802.1p/q style
tag or as the ToS field in the IP header. The information may also be available
out-of-band depending on the host DDI.
Connection States
Table B-1 describes the AR6000 WLAN connection states:
Table B-1. AR6000 Connection States
Connection State
Description
DISCONNECTED
In this state, the AR6000 device is not connected to a wireless
network. The device is in this state after reset when it sends the
WIRELESS MODULE <20>READY<44> EVENT, after it processes a
DISCONNECT command, and when it loses its link with the
access point (AP) that it was connected to. The device signals a
transition to the DISCONNECTED state with a <20>DISCONNECT<43>
event.
CONNECTED
In this state, the AR6000 device is connected to wireless networks.
The device enters this state after successfully processing a
CONNECT, which establishes a connection with a wireless
network. The device signals a transition to the CONNECTED state
with a <20>CONNECT<43> event.
Message Types
WMI uses commands, replies, and events for the control and configuration of
the AR6000 device. The control protocol is asynchronous. Table B-2 describes
AR6000 message types:
Table B-2. AR6000 Message Types
Message Type
Description
Commands
Control messages that flow from the host to the device
Replies/Events
Control messages that flow from the device to the host.
The device issues a reply to some WMI commands, but not to others.
The payload in a reply is command-specific, and some commands do
not trigger a reply message at all. Events are control messages issued
by the device to signal the occurrence of an asynchronous event.
WMI Message Format
All WMI control commands, replies and events use the header format:
WMI_CMD_HDR Header Format
{
UINT16 id
This 16-bit constant identifies which WMI command the host is issuing,
which command the target is replying to, or which event has occurred.
WMI_CMD_HDR
}
A variable-size command-, reply-, or event-specific payload follows the
header. Over the interconnect, all fields in control messages (including
WMI_CMD_HDR and the command specific payload) use 32-bit little Endian
byte ordering and fields are packed. The AR6000 device always executes
commands in order, and the host may send multiple commands without
waiting for previous commands to complete. A majority of commands are
processed to completion once received. Other commands trigger a longer
duration activity whose completion is signaled to the host through an event.
Command Restrictions
Some commands may only be issued when the AR6000 device is in a certain
state. The host is required to wait for an event signaling a state transition
before such a command can be issued. For example, if a command requires
the device to be in the CONNECTED state, then the host is required to wait
for a <20>CONNECT<43> event before it issues that command.
The device ignores any commands inappropriate for its current state. If the
command triggers a reply, the device generates an error reply. Otherwise, the
device silently ignores the inappropriate command.
Command and Data Synchronization
WMI provides a mechanism for a host to advise the device of necessary
synchronization between commands and data. The device implements
synchronization; no implicit synchronization exists between endpoints.
The host controls synchronization using the <20>SYNCHRONIZE<5A> command
over the control channel and synchronization messages over data channels.
The device stops each data channel upon receiving a synchronization message
on that channel, processing all data packets received prior to that message.
After the device receives synchronization messages for each data endpoint
and the <20>SYNCHRONIZE<5A> command, it resumes all channels.
When the host must guarantee a command executes before processing new
data packets, it first issues the command, then issues the <20>SYNCHRONIZE<5A>
command and sends synchronization messages on data channels. When the
host must guarantee the device has processed all old data packets before a
processing a new command, it issues a <20>SYNCHRONIZE<5A> command and
synchronization messages on all data channels, then issues the desired
command.

ADD_WOW_PATTERN
Synopsis
The host uses this command to add a pattern to the WoW pattern list; used for
pattern-matching for host wakeups by the WoW module. If the host mode is asleep
and WoW is enabled, all packets are matched against the existing WoW patterns. If a
packet matches any of the patterns specified, the target will wake up the host. All
non-matching packets are discarded by the target without being sent up to the host.
Command
wmiconfig <20>addwowpattern <list-id> <filter-size> <filter-offset>
<pattern> <mask>
Command Parameters
A_UINT8 filter_list_id ID of the list that is to include the new pattern
A_UINT8 filter_size Size of the new pattern

CONNECT_CMD
Synopsis
New connect control information (connectCtrl) is added, with 32 possible modifiers.
CONNECT_SEND_REASSOC
Valid only for a host-controlled connection to a
particular AP. If this bit is set, a reassociation frame is
sent. If this bit is clear, an association request frame is
sent to the AP.
CONNECT_IGNORE_WPAx_GROUP_CIPHER
No group key is issued in the CONNECT command,
so use the group key advertised by the AP. In a target-
initiated roaming situation this allows a STA to roam
between APs that support different multicast ciphers.
CONNECT_PROFILE_MATCH_DONE
In a host-controlled connection case, it is possible that
during connect, firmware may not have the
information for a profile match (e.g, when the AP
supports hidden SSIDs and the device may not
transmit probe requests during connect). By setting
this bit in the connection control information, the
firmware waits for a beacon from the AP with the
BSSID supplied in the CONNECT command. No
additional profile checks are done.
CONNECT_IGNORE_AAC_BEACON
Ignore the Admission Capacity information in the
beacon of the AP
CONNECT_ASSOC_POLICY_USER
When set, the CONNECT_SEND_REASSOC setting
determines if an Assoc or Reassoc is sent to an AP

CREATE_PSTREAM
Synopsis
The host uses this command to create a new prioritized data endpoint between the
host and the AR6000 device that carries a prioritized stream of data. If the AP that the
device connects to requires TSPEC stream establishment, the device requests the
corresponding TSPEC with the AP. The maximum and minimum service interval
ranges from 0 <20> 0x7FFFFFFF (ms), where 0 = disabled. The device does not send a
reply event for this command, as it is always assumed the command has succeeded.
An AP admission control response comes to the host via a WMI_CAC_INDICATION
event, once the response for the ADDTS frame comes.
Examples of cases where reassociation is generated (when WMM) and cases where
ADDTS is generated (when WMM and enabling ACM) are when:
Changing UAPSD flags in WMM mode, reassociation is generated
Changing the interval of sending auto QoS Null frame in WMM mode;
reassociation is not generated
Issuing a command with same previous parameters in WMM mode and enabling
ACM, an ADDTS request is generated
Changing the interval of a QoS null frame sending in WMM mode and enabling
ACM, an ADDTS request is generated
Issuing the command in disconnected state, reassociation or ADDTS is not
generated but the parameters are available after (re)association

The WMI message interface is used mostly for wireless control messages to a wireless
module applicable to wireless module management regardless of the target platform
implementation. However, some commands only peripherally related to wireless
management are desired during operation. These wireless extension commands may
be platform-specific or implementation-dependent.

SET_BSS_FILTER
Synopsis
The host uses this to inform the AR6000 device of the types of networks about which
it wants to receive information from the <20>BSSINFO<46> event. As the device performs
either foreground or background scans, it applies the filter and sends <20>BSSINFO<46>
events only for the networks that pass the filter. If any of the bssFilter or the ieMask
filter matches, a BSS Info is sent to the host. The ieMask currently is used as a match
for the IEs in the beacons, probe reponses and channel switch action management
frame. See also <20>Scan and Roam<61> on page C-1.
The BSS filter command has been enhanced to support IE based filtering. The IEs can
be specified as a bitmask through this command using this enum.

SET_CHANNEL_PARAMETERS
Synopsis
Configures various WLAN parameters related to channels, sets the wireless mode,
and can restrict the AR6000 device to a subset of available channels. The list of
available channels varies depending on the wireless mode and the regulatory
domain. The device never operates on a channel outside of its regulatory domain. The
device starts to scan the list of channels right after this command.
Command
wmiconfig eth1 --wmode <mode> <list>
Command Parameters
UINT8 phyMode See Values below.
UINT8 numberOfChannels
Number of channels in the channel array that
follows. If = 0, then the device uses all of the
channels permitted by the regulatory domain
and by the specified phyMode.
UINT16 channel[numberOfChannels]
Array listing the subset of channels (expressed
as frequencies in MHz) the host wants the
device to use. Any channel not permitted by
the specified phyMode or by the specified
regulatory domain is ignored by the device.

=====================================================================
Name
SET_DISC_TIMEOUT
Synopsis
The host uses this command to configure the amount of time that the AR6000 should
spend when it attempts to reestablish a connection after losing link with its current
BSS. If this time limit is exceeded, the AR6000 send a <20>DISCONNECT<43> event. After
sending the <20>DISCONNECT<43> event the AR6000 continues to attempt to reestablish a
connection, but they do so at the interval corresponding to a foreground scan as
established by the <20>SET_SCAN_PARAMS<4D> command.
A timeout value of 0 indicates that the AR6000 will disable all autonomous roaming,
so that the AR6000 will not perform any scans after sending a <20>DISCONNECT<43>
event to the host. The state is maintained until a shutdown or host sets different
timeout value from 0.
Command
wmiconfig eth1 --disc=<timeout in seconds>
Command Parameters
UINT8 disconnectTimeout
Specifies the time limit (in seconds) after
which a failure to reestablish a connection
results in a <20>DISCONNECT<43> event
Command Values
None
Reset Values
disconnectTimeout is 10 seconds
Restrictions
This command can only be issued while in a DISCONNECTED state
=====================================================================
Name
SET_FIXRATES
Synopsis
By default, the AR6000 device uses all PHY rates based on mode of operation. If the
host application requires the device to use subset of supported rates, it can set those
rates with this command. In 802.11g mode, the AR6000 device takes the entire
802.11g basic rate set and the rates specified with this command and uses it as the
supported rate set.
This rate set is advertised in the probe request and the assoc/re-assoc request as
supported rates. Upon successful association, the device modifies the rate set pool
using the: intersection of AP-supported rates with the union of the 802.11g basic rate
set and rates set using this command. The device picks transmission rates from this
pool based on a rate control algorithm.
Command
TBD
Command Parameters
A_UINT16 fixRateMask;
The individual bit is an index for rate table,
and setting the that index to 1 would set that
corresponding rate. E.g., fixRateMask = 9
(1001) sets 1 Mbps and 11 Mbps.

Name
SET_IBSS_PM_CAPS
Synopsis
Used to support a non-standard power management scheme for an ad hoc wireless
network consisting of up to eight stations (STAs) that support this form of power
saving (e.g., Atheros-based STAs). A thorough understanding of IEEE 802.11 ad hoc
networks is required to use this command effectively.
Command
wmiconfig eth1 --ibsspmcaps --ps=<enable/disable>
--aw=<ATIM Windows in ms>
--ttl=<Time to live in number of beacon periods>
--to=<timeout in ms>
Command Parameters
UINT8 power_saving
= 0
The non-standard power saving scheme is
disabled and maximum throughput (with no
power saving) is obtained.
= 1
Ad hoc power saving scheme is enabled (but
throughput may be decreased)
UINT16 atim_windows
Specifies the length (in ms) of the ad hoc traffic
indication message (ATIM) windows used in an ad
hoc network. All Atheros-based STAs that join the
network use this duration ATIM window.
The duration is communicated between wireless
STAs through an IE in beacons and probe responses.
The host sets atim_windows to control trade-offs
between power use and throughput. The value
chosen should be based on the beacon interval (see
the <20>SET_BEACON_INT<4E> command) on the
expected number of STAs in the IBSS, and on the
amount of traffic and traffic patterns between STAs.
UINT16 timeout_value
Specifies the timeout (in ms). The value is the same
for all ad hoc connections, but tracks separately for
each.
Applicable only for a beacon period and used to
derive actual timeout values on the Tx and Rx sides.
On the Tx side, the value defines a window during
which the STA accepts the frame(s) from the host for a
particular connection. Until closed, the window
restarts with every frame received from the host. On
the Rx side, indicates the time until which the STA
continues accepting frames from a particular
connection. The value resets with every frame
received. The value can be used to determine the
trade off between throughput and power.
Default = 10 ms
UINT8 ttl
Specifies the value in number of beacon periods. The
value is used to set a limit on the time until which a
frame is kept alive in the AR6001 before being
discarded. Default = 5
Command Values
None
Reset Values
By default, power_saving is enabled with atim_window = 20 ms
Restrictions
Can only be issued before the AR6000 starts an ad hoc network

Name
SET_LISTEN_INT
Synopsis
The host uses this command to request a listen interval, which determines how often
the AR6000 device should wake up and listen for traffic. The listen interval can be set
by the TUs or by the number of beacons. The device may not be able to comply with
the request (e.g., if the beacon interval is greater than the requested listen interval, the
device sets the listen interval to the beacon interval). The actual listen interval used
by the device is available in the <20>CONNECT<43> event.
Command
wmiconfig eth1 --listen=<#of TUs, can range from 15 to 3000>
--listenbeacons=<#of beacons, can range from 1 to 50>

Name
SET_POWER_MODE
Synopsis
The host uses this command to provide the AR6000 device with guidelines on the
desired trade-off between power utilization and performance.
In normal power mode, the device enters a sleep state if they have nothing to do,
which conserves power but may cost performance as it can take up to 2 ms to
resume operation after leaving sleep state.
In maximum performance mode, the device never enters sleep state, thus no time
is spent waking up, resulting in higher power consumption and better
performance.
Command
TBD
Command Parameters
UINT8 powerMode
WMI_POWER_MODE value
{
REC_POWER = 1
(Recommended setting) Tries to conserve
power without sacrificing performance
MAX_PERF_POWER = 2
Setting that maximizes performance at
the expense of power
All other values are reserved
} WMI_POWER_MODE
Command Values
See command parameters
Reset Values
powerMode is REC_POWER
Restrictions
This command should only be issued in the DISCONNECTED state for the
infrastructure network.
For a PM-disabled ad hoc network, the power mode should remain in
MAX_PERF_POWER.
For a PM-enabled ad hoc network, the device can have REC_POWER or
MAX_PERF_POWER set, but either way it must follow the power save ad hoc
protocol. The host can change power modes in the CONNECTED state.
Host changes to the PS setting when the STA is off the home channel take no effect
and cause a TARGET_PM_FAIL event.

Name
SET_ROAM_CTRL
Synopsis
Affects how the AR6000 device selects a BSS. The host uses this command to set and
enable low RSSI scan parameters. The time period of low RSSI background scan is
mentioned in scan period. Low RSSI scan is triggered when the current RSSI
threshold (75% of current RSSI) is equal to or less than scan threshold.
Low RSSI roam is triggered when the current RSSI threshold falls below the roam
threshold and roams to a better AP by the end of the scan cycle. During Low RSSI
roam, if the STA finds a new AP with an RSSI greater than roam RSSI to floor, during
scan, it roams immediately to it instead of waiting for the end of the scan cycle. See
also <20>Scan and Roam<61> on page C-1.

Name
SET_SCAN_PARAMS
Synopsis
The host uses this command to set the AR6000 scan parameters, including the duty
cycle for both foreground and background scanning. Foreground scanning takes
place when the AR6000 device is not connected, and discovers all available wireless
networks to find the best BSS to join. Background scanning takes place when the
device is already connected to a network and scans for potential roaming candidates
and maintains them in order of best to worst. A second priority of background
scanning is to find new wireless networks.
The device initiates a scan when necessary. For example, a foreground scan is always
started on receipt of a <20>CONNECT_CMD<4D> command or when the device cannot find
a BSS to connect to. Foreground scanning is disabled by default until receipt of a
CONNECT command. Background scanning is enabled by default and occurs every
60 seconds after the device is connected.
The device implements a binary backoff interval for foreground scanning when it
enters the DISCONNECTED state after losing connectivity with an AP or when a
CONNECT command is received. The first interval is ForegroundScanStartPeriod,
which doubles after each scan until the interval reaches ForegroundScanEndPeriod.
If the host terminates a connection with DISCONNECT, the foreground scan period
is ForegroundScanEndPeriod. All scan intervals are measured from the time a full
scan ends to the time the next full scan starts. The host starts a scan by issuing a
<20>START_SCAN<41> command. See also <20>Scan and Roam<61> on page C-1.
Command
wmiconfig eth1 --scan --fgstart=<sec> --fgend=<sec> --bg=<sec> --
act=<msec> --pas=<msec> --sr=<short scan ratio> --scanctrlflags

Command Parameters
UINT16 fgStartPeriod
First interval used by the device when it
disconnects from an AP or receives a
CONNECT command, specified in seconds (0<>
65535). If = 0, the device uses the reset value.
If = 65535, the device disables foreground
scanning.
UINT16 fgEndPeriod
The maximum interval the device waits between
foreground scans specified in seconds (from
ForegroundScanStartPeriod to 65535). If = 0, the
device uses the reset value.
UINT16 bgScanPeriod
The period of background scan specified in
seconds (0<>65535). By default, it is set to the reset
value of 60 seconds. If 0 or 65535 is specified, the
device disables background scanning.
UINT16 maxactChDwellTime
The period of time the device stays on a
particular channel while active scanning. It is
specified in ms (10<31>65535). If the special value of
0 is specified, the device uses the reset value.
UINT16 PasChDwellTime
The period of time the device remains on a
particular channel while passive scanning. It is

Name
BSSINFO
Synopsis
Contains information describing one or more BSSs as collected during a scan.
Information includes the BSSID, SSID, RSSI, network type, channel, supported rates,
and IEs. BSSINFO events are sent only after the device receives a beacon or probe-
response frame that pass the filter specified in the <20>SET_BSS_FILTER<45> command.
BSSINFO events consist of a small header followed by a copy of the beacon or probe
response frame. The 802.11 header is not present. For formats of beacon and probe-
response frames please consult the IEEE 802.11 specification.
The beacons or probe responses containing the IE specified by the
WMI_BSS_FILTER_CMD are passed to the host through the
WMI_BSSINFO_EVENT. The event carries a 32-bit bitmask that indicates the IEs that
were detected in the management frame. The frame type field has been extended to
indicate action management frames. This would be helpful to route these frames
through the same event mechanism as used by the beacon processing function.
If the bssFilter in the SET_BSS_FILTER matches, then the ieMask is not relevant
because the BSSINFO event is sent to the host. If the bssFilter doesnot match in the
beacons/probe respones, then the ieMask match dictates whether the BSSINFO
event is sent to the host. In the case of action management frames, the ieMask is the
filter that is applied.

WMI Extension Commands
The WMI EXTENSION command is used to multiplex a collection of
commands that:
Are not generic wireless commands
May be implementation-specific
May be target platform-specific
May be optional for a host implementation
An extension command is sent to the AR6000 targets like any other WMI
command message and uses the WMI_EXTENSION. The first field of the
payload for this EXTENSION command is another commandId, sometimes
called the subcommandId, which indicates which extension command is
being used. A subcommandId-specific payload follows the subcommandId.
All extensions (subcommandIds) are listed in the header file include/wmix.h.
See also <20>WMI Extension Events<74> on page B-58.
